Referring to the drawings in detail, 1 denotes a stationary base which is circular in contour. and which is mounted on a series of vertically extending short supports 2. Eachof'the supports 2, is formed with a vertically disposed" central bore 3 and also at the lower end thereof with a counterbore 4.

v Arranged above and spaced from the base 1',

is a stationary platform 5, which is circular in contour and is substantially the same di ameter'as the diameter of the base I. Inter-' posed betw'een the platform 5 and the base 1, is aseries Ofyertically disposed support 111g standards 6, eachprovided at 1ts upper and lowerends with aflange 7. Each of the standardsfi is formed with a vertically disposed bore 8 which registers with the bore 3 in a support 2. The standardsti are ar-- ranged in alinement with the supports 2,

and the bores 8 of the standards 6, register with openings 9 formed in the balsel', and

bolts 12 extend into the counterbore 4, and carries a nut 13, and as the' 'bolt 12 is pro videdat its other end with ahead-12, seated o outwardly from the platform egg.

The platform at its axis is formed with an opening 1 1, and is furthermore provided in diametrical alinement wlththe opening 14:, with an opening 15 arrzmgedin proximity to the guide 11.. interposed between the platform 5 and "the base 1, on=each side 01": each of theopenings 14; and 15, is a pair oroppositely disposed brace members 16,

1 each of which is secured by the hold fast to the base 1,

threaded.

device 17, to the platfornr or table 5, and by the hold fast device 18,.to the base 1. Each of the brace members 16,, is formed with a transversely extending opening 19,

whichisdisposed in parallelism with respect and? has the wall thereof Mounted on the base and projecting up through the platform or table 5, isa saw guide, and which consists of a .pair of vertically disposed posts 20, 21,;arranjged in aline ment with each. other, and so disposed that the post extends up through the'opening 14; and the post21eXtends up through the opening 15.f The post 20, as well as the post 21, is formed a guide passage 22, for the saw 23. The guide passages 22 of the posts are arranged in ahnement; and the upg per portion of the guide passage 22, in each post,is' or" greater width than the lower portion, as indicated at 24 The upper portion ofthe post 20, is connected to the upper portion oi the post 21, by plates 25, andwhich are arranged 1D spaced relation 1n such a- .1 manner, so as to form acontinuiation of the upper. portion 2 1 of the guide passage 22. Thefwidth of the upper portion 24', of the guide passage22, is slightly greater than the thickness of the saw back 26. Mounted on 1' and secured to the top of the posts 20, 21,
